Why it's free to use

  • Filed June 1, 1988 and granted July 25, 1989. A patent filed before June 8, 1995 lasts 17 years from grant or 20 from filing, whichever is longer, so its term ended June 1, 2008.
  • Any extension is capped at five years, so it can't still be in force.
  • We haven't checked its US family, and a later related patent could still be in force. We check US rights only.
